%X Leaching characteristics of heavy metals during cement stabilization of fly ash from municipal solid waste incinerator was investigated.We investigated stabilization of heavy metal,such as Cd,Pb,Cu and Zn in fly ash from municipal solid waste incinerator,through the national standard method,with the factors as follows: addition quantity of cement and Na2S,curing time,and pH of leaching liquor.The results show that the more addition the less of heavy metal leached, except Pb which is sensitive to pH of the leachate,and the worse effect of Cd. Cement/fly ash=10% is the most appropriate parameter according to national standard method.The hydratation of cement finished basically and stabilization of heavy metal doesn't vary after curing for 1 day.The mixtures of cement and fly ash have excellent adaptability to environmental pH;the pH of leachate maintain at 7 steadily when pH of leaching liquor varied from 3 to 11.
